Step-by-Step Application Guide
1. Substrate Preparation
Ensure the wall surface is structurally sound, clean, dry, and free from dust, oil, grease, or peeling materials. The application site temperature should be between 5°C and 40°C.
2. Stirring
YY-512A is a ready mixed wall putty. No water should be added. Open the plastic bucket and stir the paste thoroughly with an electric mixer for 1–2 minutes to achieve perfect thixotropic workability before application.
3. Scraping / Troweling
Apply the compound using a stainless steel trowel or putty knife. Apply 2 coats for an optimum flat surface, ensuring the thickness of each individual layer is kept under 1.5mm. Allow the first coat to dry completely before applying the second.
4. Sanding & Finish Coating
After the final coat dries completely (usually 24 hours), lightly sand the surface with fine sandpaper (320 grit recommended) to achieve a mirror-smooth finish. Wipe away dust, and the wall is fully ready for premium decorative primers and paints.
